Description

Technical Field

[0001] This utility model relates to the field of dental medical device technology, specifically a disposable isolation sleeve for dental light curing machines. Background Technology

[0002] Dental light curing machines (also known as light curing lamps) are one of the core pieces of equipment in dental clinical treatment. They emit light of a specific wavelength (usually blue light) to induce a polymerization and curing reaction in dental resin materials (such as filling resin, bonding resin, etc.). They are widely used in dental filling, tooth defect repair, orthodontic bracket bonding and other treatment scenarios.

[0003] Because dental light-curing machines require close-range operation inside the patient's mouth, the front connector (the end component that emits light) and the outer side of the machine inevitably come into contact with the patient's saliva, blood, and other bodily fluids. Without effective isolation measures, this can easily lead to cross-infection between different patients. Currently, disposable isolation sleeves are commonly used in clinical practice to protect light-curing machines. These sleeves are typically thin, cylindrical structures that are placed over the front connector and part of the outer side of the machine. This not only prevents direct contact between the equipment and bodily fluids but also reduces the frequency of equipment disinfection, minimizing wear and tear caused by frequent disinfection, and simplifying the operating procedures for healthcare workers.

[0004] However, in actual clinical applications, existing disposable isolation sleeves still have significant shortcomings in terms of fit and installation smoothness with dental light-curing machines, mainly in the following two aspects: Problem with the front connector air chamber: The existing isolation sleeve is a closed cylindrical structure. When it is fitted into the front connector of the UV curing machine, the front end of the front connector extends into the isolation sleeve first, resulting in a closed air chamber between the inner wall of the isolation sleeve and the front end of the front connector. Because the air cannot be expelled quickly, the air chamber generates reverse air pressure, which prevents the front connector from going further in. This prevents the isolation sleeve from being fully fitted to the preset position, affecting the protective effect and ease of operation.

[0005] Installation issues such as jamming and wrinkling: Dental light-curing machines typically have function buttons (such as power adjustment buttons and mode switching buttons) and raised structures (such as anti-slip textures and interface protective sleeves) on the side of the machine body. The existing isolation sleeve has a uniform diameter opening at the tail. During the process of fitting it into the machine body, the tail opening is easily jammed by the buttons or raised structures. This not only causes installation jamming but also causes wrinkles to form on the isolation sleeve at the jamming point, which disrupts the tight fit between the isolation sleeve and the machine body. There is a risk that bodily fluids may seep in through the gaps in the wrinkles, and it also affects the operating feel.

[0006] In view of the shortcomings of the existing technology, there is an urgent need for an isolation sleeve structure that can solve the problems of air chamber obstruction and installation jamming and wrinkling, so as to improve its compatibility with dental light curing machines and clinical user experience. Utility Model Content

[0007] The purpose of this invention is to overcome the two core problems of existing disposable isolation sleeves for dental light-curing machines: "air chamber obstruction at the front connector" and "installation jamming and wrinkles", and to provide an isolation sleeve with an optimized structure.

[0008] The technical solution to achieve the purpose of this utility model is: A disposable isolation sleeve for a dental light curing machine, the isolation sleeve being an integrally formed cylindrical structure comprising a front connector adapter section, a main cylindrical section, and a tail opening section connected sequentially along the axial direction; At least one vent is provided on the main body section, and the vent penetrates the inner and outer walls of the main body section to discharge the air in the closed air chamber formed when the front connector adapter section is fitted into the front connector of the dental light curing machine. The tail opening section has a flared, gradually widening structure, allowing the buttons and protruding parts of the dental light curing machine to pass through smoothly.

[0009] The diameter of the exhaust port is no greater than 3mm.

[0010] The vent is located in the middle of the main cylindrical section.

[0011] The inner diameter of the tail opening gradually increases from the end closer to the main body cylindrical section to the end farther away from the main body cylindrical section. When fitted into the UV curing machine body, the buttons, protrusions, and other protruding structures of the machine body smoothly enter through the wide diameter of the tail opening, and then slide along the gradually curved surface into the transition straight section and the machine body adapter section, effectively reducing frictional resistance and jamming during installation and preventing wrinkles from forming on the isolation sleeve.

[0012] The isolation sleeve is made of medical-grade transparent plastic, which is selected from one of polyvinyl chloride (PVC), polyethylene (PE) or polypropylene (PP).

[0013] The inner diameter of the front connector adapter section is adapted to the outer diameter of the front connector of the dental light curing machine, and the inner diameter of the main body section is adapted to the outer diameter of the dental light curing machine body.

[0014] The isolation sleeve of this utility model, through the above-described structural improvements, has the following advantages compared to the prior art: Solving the problem of air chamber obstruction: The central exhaust port can discharge the air in the closed air chamber formed when the front connector is inserted in real time, completely eliminating air pressure obstruction, allowing the front connector to be inserted into the preset position in one go without repeated adjustments, thus improving installation efficiency; Eliminating jamming and wrinkles: The flared tail section with a gradual guide design allows the protruding parts of the body to pass through easily, avoiding installation jamming. At the same time, it ensures that the isolation sleeve fits tightly against the outer wall of the body without any wrinkles or gaps, reducing the risk of bodily fluid infiltration. Improved fit and protection: The front connector adapter section fits tightly to the front connector, and the body adapter section fits seamlessly to the body. Combined with the anti-wrinkle design of the flared tail, the overall protective sealing is significantly improved, effectively blocking the path of cross-infection. Optimizes clinical operation experience: Improved installation smoothness allows medical staff to quickly replace isolation covers, reducing preparation time for diagnosis and treatment. At the same time, the transparent material does not affect the operation and observation of the light curing machine, meeting clinical needs. Attached Figure Description

[0016] The markings in the diagram are as follows: 1. Front connector adapter section; 2. Main cylinder section; 3. Tail opening section; 4. Exhaust port. Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this is not intended to limit the present invention. Example

[0018] like Figure 1 As shown, a disposable isolation sleeve for a dental light curing machine is provided. The isolation sleeve is an integrally formed cylindrical structure, including a front connector adapter section 1, a main cylindrical section 2, and a tail opening section 3 connected sequentially along the axial direction. At least one vent hole 4 is provided on the main body cylindrical section 2. The vent hole 4 penetrates the inner and outer walls of the main body cylindrical section 2 and is used to discharge the air in the closed air chamber formed when the front connector adapter section 1 is fitted into the front connector of the dental light curing machine. The tail opening section 3 has a flared, gradually widening structure, allowing the buttons and protruding parts of the dental light curing machine to pass through smoothly.

[0019] The diameter of the exhaust port 4 is 1mm-3mm.

[0020] The exhaust port 4 is located in the middle of the main cylinder section 2.

[0021] The inner diameter of the tail opening section 3 gradually increases from the end closer to the main body cylindrical section 2 to the end farther away from the main body cylindrical section 2. When the UV curing machine body is fitted, the buttons, protrusions and other protruding structures of the machine body can smoothly enter through the wide diameter of the tail opening section 3, and then slide into the main body cylindrical section 2 along the gradually curved surface, effectively reducing frictional resistance and jamming during installation and preventing wrinkles from forming on the isolation sleeve.

[0022] The isolation sleeve is made of medical-grade transparent plastic, which is selected from one of polyvinyl chloride (PVC), polyethylene (PE) or polypropylene (PP).

[0023] The inner diameter of the front connector adapter section 1 is adapted to the outer diameter of the front connector of the dental light curing machine, and the inner diameter of the main body section 2 is adapted to the outer diameter of the dental light curing machine body.

[0024] Installation and usage process Medical staff take out the isolation sleeve of this embodiment, hold the tail opening section 3, and align the opening of the front connector adapter section 1 with the front connector of the dental light curing machine. Slowly push the isolation sleeve so that the front connector gradually extends into the front connector adapter section 1. At this time, the air in the closed air chamber formed by the front end 1 of the front connector and the inner wall of the front connector adapter section is discharged outward through the exhaust hole 4 of the main body section 2. Without air pressure obstruction, the front connector can be smoothly inserted to the bottom of the front connector adapter section 1. Continue pushing the isolation sleeve so that the body of the UV curing machine passes through the main body section 2 of the tail opening section in sequence, and finally the main body section 2 is completely fitted onto the outside of the machine body. The whole process is smooth and there is no jamming. The isolation sleeve fits tightly against the outer wall of the machine body without any wrinkles. After the treatment, simply pull the light curing machine out from the tail opening section 3 of the isolation sleeve, and it can be quickly removed and discarded, completing the single-use process.
